4 Vehicle / Infrastructure interaction Source scale interactions Contact (wheel/rail tyre/road) Vehicle / Track / Ground External aerodynamics Infrastructure scale interactions Traffic / Infrastructure management Impact on surrounding environment Ground-borne noise and vibrations

5 Topics Vibro-acoustics and noise reduction Contact (non linear phenomena in the contact zone) Rolling noise / Squeal noise Vibration sources Vibrations induced in the ground Optimization of low noise road surfaces Dynamic modelling of traffic

6 Applications Models of physical sources Prediction tools for noise and vibration levels Noise and vibration impacts on surrounding buildings Dynamic modelling of traffic noise Optimization for noise and vibration mitigation Monitoring of the infrastructure CNAM, Paris, September 27th 2010

7 Methodologies Contact: Time domain modelling approaches Comparison of different modeling approaches (analytical, semi-analytical, numeric) Identification of physical parameters Influence of Roughness / Texture Measurement methods Comparison between predicted and measured attenuation CNAM, Paris, September 27th 2010
